When will the root planting method of Dahlia be planted?

Dahlia flowers that are big, is very good-looking, is very popular, Dahlia planting is generally root planting, to see how Dahlia root planting method is? When is the best time to start planting Dahlia tubers:

Prepare tools and materials:

Spade, small pruning knife, pillar, watering pot with shower head, nutrient fertilizer with slow fertility release, etc.

Time selection:

In April, once the earth starts to warm up again, take out the dahlia roots stored in the storage room (if you buy them that year, try to choose healthy and fat roots).

1. Remove dry roots, and if there are too many tuber roots (split them with a small pruning knife), pay attention to leaving adventitious buds and some lateral roots on each rhizome.

2. Dig-dig a pit about 20cm deep, loosen the soil, and remove boulders and weed roots. If the soil has a high sand content, cultivate it with soil compost or compost.

3. In order to provide the nutrition especially nitrogen fertilizer that Dahlia needs in the future, add slow-release fertilizer while weeding the soil, and pay attention to apply fertilizer according to the quantity on the product description.

4. In order not to damage the tuber root, set up before the Dahlia peanut root-the pillar is in a pit about 15cm deep. Place the bulb flat at the bottom of the pit with the bud close to the pillar.

5. Fill the pit with broken soil. In order to make the bulbs come into full contact with the soil, gently flatten the pit with your feet, and then water it thoroughly like a light rain.

II. Setting up pillars and pruning

In July, dahlias planted at the beginning of spring are springing up like bamboo shoots after a spring rain. It's time to set up pillars, if not at the time of planting. In order to cultivate large and beautiful flowers, it is recommended to carry out cutting.

6. Set up a pillar at the foot of each dahlia before the rhizome is overwhelmed by the weight of leaves and flowers. Be careful not to break the bulbs.

7. The pillar had better leave the rhizome 5cm and tie the rhizome and strut loosely with plastic or wine coconut leaf fiber rope.

Note: don't pull the roots and pillars too tight.

8. in order to cultivate large flowers, use a sharp small pruning knife to eliminate the leaf axils growing under the leaves, leaving only the buds growing on the rhizome. At the same time, eliminate small side branches.

9. Short dahlias do not need to set up pillars, and clumps of branches and leaves can support flowers. However, in order to prevent bolting and reduce the burden of bulbs, attention should be paid to the timely elimination of withered flowers. Timely elimination of withered flowers can also effectively promote the production of new buds.

Management after March and October

In October and October, when the Dahlia season is over, use trimming or sharp scissors to cut off all the root branches at the 10cm. Don't touch the leaves, except for the withered leaves, of course.

11. Wait until the plant has withered completely before pulling out the dahlias. If pulled too early, it may seriously damage its storage and affect future reproduction.

12. When the plant has withered completely, use a long-handled fork shovel, pull it out carefully, and be careful not to destroy its roots.

13. After drying in the open air for several hours, remove the soil and dead leaves from the bulbs, cut off the excess root branches (keep about 5cm), write down the name and color, and tie the label.

14. Store them in a wooden box in a dry and ventilated place. If you are afraid of erosion, you can store them in a net bag and hang them up. Pay attention to regularly observe their health status.

15. In places where frost and ice are rare, the Dahlia bulb can be left in the ground. Cut off all withered branches and leaves from the 5cm above the ground. Cover with 20-30cm thick dry leaves or straw.

IV. Harvesting and storage of Dahlia tuber roots

Dahlia is not cold-resistant, mainly because the root tuber can not be frozen, Dahlia root at 0. Dormancy begins at 5 ℃ and frostbite occurs when the temperature is below 0 ℃, so it is impossible to overwinter in open field in North China, and tubers should be harvested before the early frost.

After frost, the plants and leaves withered and withered. The stems and leaves of the aboveground parts should be cut off immediately and the roots should be dug out. Potted plants can be removed from the pot or even put into the greenhouse for storage. The varieties should be checked and selected before harvest to ensure the purity of the varieties.

Note:

Before storage, the withered stems and leaves should be cut off about the 15cm from the root neck. In order to prevent sprain of the root neck (the future sprouting part), the root tuber should be dug out the whole pier.

After digging out the root, dry it in the sun for 3 days before collecting it. In order to prevent frost at night, the roots can be covered with Reed curtains or straw. Waiting

After the soil on the root is dry, shake off the soil, classify it by variety, tie the sign, and put it in a greenhouse with a temperature of not more than 5 ℃. At this time, keeping a constant temperature of about 3-5 ℃ and preventing excessive temperature is the key to preserving the root, because too high will make the foot buds in the neck of the root germinate ahead of time, consume water and nutrients, and affect the bulb, while too low will cause the bulb to rot.

5. Disinfection and sterilization

In addition, the storage place should be sterilized. When setting, the root neck is placed upward on the floor of the greenhouse. In order to prevent premature germination and heat of rotten roots, it is generally beneficial to stack 3-5 layers and bury them with slightly wet sand.

During winter storage, it is necessary to check regularly and cut off the rotten and useless roots in time. If you find that the sand is too dry, do not water the root directly. After taking out the root tuber, spray the sand and wet it to the degree of moisture, and then bury the root again. In addition, the withered stems and leaves of potted plants can also be cut off, and the original pot can be placed in a greenhouse with a temperature of no more than 3-5 ℃ to stack up the pots and avoid direct light.

During storage, if the basin soil is too dry, it can be watered a little (the amount of water must not be too large) to keep the soil slightly moist to avoid root rot. This method is simple, but it takes up a large storage area. Another method of storage is to divide the dried roots together with the adventitious buds growing on the root neck.

After division, the cut is coated with plant ash, packed in a wooden slot or wooden box, and filled with dry sand or sawdust between the pores. Then the wooden trough or wooden box was stored under the condition of 3: 5 ℃ with good ventilation and no direct light. Do not reverse during storage. This method is not only easy to keep, but also convenient to use, and can save the storage area.

The root tubers of some varieties of dahlia are difficult to store, such as lotus chrysanthemum, honeysuckle and so on. When storing the tubers of these varieties, do not mix them with other tubers. The dried root can be placed in a wooden box or flowerpot. The root can be covered with a small amount of dry sand and stored under the condition of 3-5 ℃.

A few days before the arrival of the frost period of the potted dahlia, the above-mentioned potted dahlias can be moved into a greenhouse of 5: 10 ℃, and the flowers and buds can be removed and cultivated for about 15 to 20 days. After the nutrients are fully concentrated in the root tuber, the stems and leaves on the plant can be removed and stored in the original pot or out of the pot.

This is the end of the Dahlia root planting method. If you really like it, plant one quickly.

When will dahlias be planted? Planting time and method of Dahlia

Dahlia, also known as Tianzhu Dan, Oriental Chrysanthemum, Dahlia, etc., is a perennial herb of Compositae. Dahlia is known as the top ten famous flowers in the world, with large gorgeous flowers and rich colors, so it has high ornamental value. So, when will dahlias be planted? The planting time and method of Dahlia are introduced as follows.

First, the planting time of Dahlia

The planting time of dahlias varies according to different breeding methods. The root propagation of Dahlia is mostly planted in March-April in spring, the cuttage of Dahlia is planted in June-August, the hotbed sowing of Dahlia is in the middle and late ten days of March, the varieties of flower bed are sown in the open field in late April, and the seeds are scattered on the soil surface.

II. Planting methods of dahlias

1. Temperature management: Dahlia like cool climate, 10: 25 ℃ is the most suitable, in early spring to blossom early, the temperature during the day is about 25 ℃, more than 25 ℃ must be ventilated and cooled, the temperature in the greenhouse should be raised when the night is below 10 ℃, and cooling measures should be taken in the high temperature season.

two。 Timely fertilization: Dahlia is a fertilizer-loving plant, and there must be sufficient fertilizer supply, otherwise it is easy to cause flowers to become smaller, dim color and lower ornamental. According to the growth situation, cake fertilizer should be applied for 4 times, thin fertilizer should be applied, and fertilization is prohibited when the high temperature exceeds 30 ℃ in summer.

3. Water management: the proper reduction of watering amount of dahlia is beneficial to control the growth of the plant, promote the stem of Dahlia to be thick, the plant short and the flower large, spray water on the leaf surface as much as possible under the condition of basically satisfying its moisture in summer high temperature, at least twice a day, to make up for evaporation loss.

4. Coring and pruning: Dahlia leaves a single bud into a single plant to make it bloom early, leaving 1-2 nodes short after flowering, and the new buds can continue to bloom. The varieties with poor branching were coring in the young stage to promote their branches, and the plants were truncated from the middle of July to the first ten days of August.

5. Florescence control: if dahlias are to bloom in winter and early spring, sunshine and temperature must be controlled. Cut flowers with large colors can be produced when winter sunshine is controlled at about 14 hours and night temperature is controlled at more than 10 ℃.

6. Cut flower harvest: when the dahlia blooms at 3-4 minutes, the first batch of flowers will be cut with 2 sections in spring and the second batch with one section. It is easy to choose to harvest in the morning or evening, insert it into water immediately after harvest, and store the tuber roots in a dry place after harvest.

[editor's conclusion] Dahlia likes cool climate and is not resistant to drought and waterlogging, so it needs special attention in the process of maintenance. The above introduces the planting time and method of Dahlia. I hope it can be helpful to you!

How to plant dahlias? how to grow dahlias?

Dahlia has little difficulty in planting and good effect of slice planting, and most families can plant dahlias with a long flowering period, and the root tuber can be planted in late March, it can bloom in mid-June, and it can bloom until the period of Frosts Descent, which can not only beautify the courtyard, but also bring economic benefits to farmers, so courtyard farming is a good direction. So, how to grow dahlias? What is the method of growing dahlias? The following editor will give you a brief introduction.

The planting method of Dahlia

1. Soil: Dahlia is the most suitable for growing in loose, fertile and well-drained sandy loam, which requires rotation and moderate fertility. PH6.7-7.8 can grow well.

2. Sunshine: dahlias like light and are not tolerant to shade. If placed in a shady place for a long time, they will have poor growth, weak roots, thin leaves and thin stems, small flowers and light colors, and even some can not blossom. Therefore, potted dahlias should be placed in a sunny place. The leaves need sufficient light during the growing period, and the daily light is required to be more than 6 hours, so that the plants are strong and the flowers are large and plump. If the sunshine is less than 4 hours a day, the branching of stems and leaves and the formation of flowers and seedlings will be affected to a certain extent, especially if there is little sunshine, the flowering is not smooth, the growth of stems and leaves is poor, and it is easy to get sick.

3. Temperature: the sex likes the cool climate, the request to the ecological factor is not strict, so the adaptability is strong. During the growing period, the temperature is not strict, it can grow normally between 5-35 ℃, but 10-25 ℃ is the most suitable.

4. Watering: the amount of water can control the height of Dahlia plants. Its moisture should be controlled in the seedling stage to promote its dwarfing. In summer, in order to reduce the temperature, increase the air humidity and reduce the water evaporation of the stems and leaves of Dahlia, water should be sprayed once or twice a day. Watering once at 3: 00 to 4 p.m., the amount of water should not be too large.

5. Fertilization: Dahlia likes fertilizer, and topdressing should be applied once in 7-10 days during the growth period, or dilute liquid fertilizer should be applied 2-3 times. However, because dahlias are afraid of heat, they are often in a semi-dormant state in summer, and there is no fertilization or extremely thin fertilizer at this stage. After the plant budding, the application amount of phosphate fertilizer can be increased to make the flower bloom better. The root system of Dahlia is delicate, and thick fertilizer is avoided in the whole growth process.

6. Insect pests: the main pest problems in dahlias are powdery mildew, gray mold, bacterial wilt, virus disease, borer moth and other insect pests, which should be sprayed regularly.

7. Pruning: cultivate dahlias with small and medium-sized flowers and remove only the lateral buds on the lower nodes of the stem to make them bloom one after another. If you want to cultivate large single flowers, only the apical buds should be retained and the rest of the lateral buds should be removed. At the end of June and the beginning of July, after the first flowering, the weather is getting hotter and the plant growth slows down, which can be pruned at this time. When pruning, the stem should be twisted and drooped in the middle of the branch and between the two leaves, leaving a height of 20cm to 30cm. A few days later, part of the wound dried up and then cut. This can prevent Rain Water from pouring into the hollow stem and causing rot. It can blossom again until October.

The above is how to grow dahlias, the planting methods of dahlias, dahlias like semi-shade, the sun is too strong to affect flowering, the light time is generally 10-12 hours, when cultivating seedlings to avoid direct sunlight. Dahlias like cool climate, blooming in late September is the largest, most gorgeous, the most prosperous, but not resistant to frost, stems and leaves immediately withered after frost. During the growing period, the temperature is not strict, 8-35 ℃ can grow, 15-25 ℃ is suitable.
